In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).
The reason why you cant test the activity of Lipase in test tube 5 is because in test tube 5 the PH is low. This decrease in pH might make it difficult to detect the activity of lipase since the optimal ph of pancreatic lipase is around 8.0. generally high or low PH result to complete loss of activities of most enzymes.
The Vmax of the enzyme is 12 μmol⋅min−1
We use Michaelis-menten equation, which is given by;
Where v is velocity of reaction
Vmax = maximum rate achieved by the system
[S] = concentration of a substrate
K
= Michaelis constant
Given V
= 10
[S] = 5km
Now, we calculate Vmax:
10 = 
Km = 1
=12 μmol⋅min−1

Answer:
water motion that is non-linear in nature can cause natural disasters on shorelines.
Explanation:
these natural disasters could be on a small scale or a large scale depending on the strength of that movement of water. Rip currents and storm surges (uncommon) are two different types of hazards that can occur on the coast. In addition, a more dangerous case is a tsunami - which may be triggered by an earthquake - these are ocean waves traveling at a very high speed.
Hope that answers the question. Have a great day!
